为什么使用 multiDexEnabled (true) 允许应用程序构建但不断崩溃？
Why does use of multiDexEnabled (true) allow the app to build but constantly crash?
我正在开发的一个应用程序（基本代码不是我写的，包含许多无法删除的大型库）。在最近的 运行 中，它开始响应消息：
只有当应用程序尝试使用 运行 箭头进行构建时才会发生这种情况，它在调用 "rebuild" 或 "clean" 时成功构建。
在线包含的解决方案是使用 multiDexEnabled true (multiDex documentation here.)
使用它，我能够使用 "run" 箭头和 "rebuild" 获得建筑物。但是，在 phone 上构建并 运行 的应用程序崩溃并显示以下错误消息：

代码崩溃的地方（原因：java.lang.NoClassDefFoundError：com.myname.myapp.view.FalseActionBar$1）是在声明侦听器时。它最初是在另一个 class 扩展点击侦听器中，所以我将它引入代码中，但这没有帮助。
title.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
switch (mode) {
case NONE:
//Nothing!
break;
case BACK:
if(delegate != null){
delegate.goBack(backLocation);
}
break;
case HOME:
if(delegate != null){
delegate.goHome();
}
break;
}
}
我最初认为问题出在充气器上，但现在我相当确定一定是使用 multiDex 造成的。
multiDex 正在做什么导致 inflation 崩溃？
只需添加
android:name="android.support.multidex.MultiDexApplication"
in AndroidManifest.xml 在 application XM 标签中作为 属性.
这将解决您所有的问题。
NoClassDefFoundError 是因为您的项目在 运行 时没有获取文件。所以试试这个建议，让我知道它是否解决了。
希望您使用的是 android 工作室。
尝试将此行也添加到 gradle 文件并重新测试相同的
dexOptions {
javaMaxHeapSize "4g"
}
你需要做以下事情
在build.gradle中添加
dexOptions {
javaMaxHeapSize "4g"
}
启用 multidex
defaultConfig {
multiDexEnabled true
}
创建一个使用 MultiDexApplication 扩展的文件，如下所示
public class App extends MultiDexApplication {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
并将此 'App' class 作为应用程序 class 清单如下 -
<application
android:name=".activity.App"
我正在开发的一个应用程序（基本代码不是我写的，包含许多无法删除的大型库）。在最近的 运行 中，它开始响应消息：

代码崩溃的地方（原因：java.lang.NoClassDefFoundError：com.myname.myapp.view.FalseActionBar$1）是在声明侦听器时。它最初是在另一个 class 扩展点击侦听器中，所以我将它引入代码中，但这没有帮助。
title.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
switch (mode) {
case NONE:
//Nothing!
break;
case BACK:
if(delegate != null){
delegate.goBack(backLocation);
}
break;
case HOME:
if(delegate != null){
delegate.goHome();
}
break;
}
}
我最初认为问题出在充气器上，但现在我相当确定一定是使用 multiDex 造成的。
multiDex 正在做什么导致 inflation 崩溃？
只需添加
android:name="android.support.multidex.MultiDexApplication"
in AndroidManifest.xml 在 application XM 标签中作为 属性.
这将解决您所有的问题。
NoClassDefFoundError 是因为您的项目在 运行 时没有获取文件。所以试试这个建议，让我知道它是否解决了。
希望您使用的是 android 工作室。 尝试将此行也添加到 gradle 文件并重新测试相同的
dexOptions {
javaMaxHeapSize "4g"
}
你需要做以下事情
在build.gradle中添加
dexOptions { javaMaxHeapSize "4g" }启用 multidex
defaultConfig { multiDexEnabled true }创建一个使用 MultiDexApplication 扩展的文件，如下所示
public class App extends MultiDexApplication { @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); MultiDex.install(this); } }并将此 'App' class 作为应用程序 class 清单如下 -
<application android:name=".activity.App"
